For example, if the sequence group number hops onceevery four time domain symbols, and the sequence number and the cyclicshift hop once every two time domain symbols, the sequence hops onceevery two time domain symbols. Of course, the number of time domainsymbols included in time domain hopping units of all sequence parametersmay also be the same. The sequence parameter is used for generating thesequence, and for example, includes a sequence group number and/or asequence number. The R2 time domain symbols include the channels orsignals, the R3 time domain symbols include the channels or signals.Alternatively, time domain symbols that do not include the channels orsignals may exist in the R2 time domain symbols, and time domain symbolsthat do not include the channels or signals may exist in the R3 timedomain symbols.

Through the above solution, the code domain information of themeasurement reference signal has a hopping unit, which can reduce theinter-cell interference of the measurement reference signal, increasesthe capacity and coverage of the measurement reference signal to someextent, and reduces the signaling overhead. Meanwhile, the sequenceparameter has a hopping unit so that the time domain OCC can be appliedto the measurement reference signal. Therefore, the problem of lack ofthe technology of increasing the capacity or coverage of the measurementreference signal in the NR in the related art is solved.

In one embodiment, the step of determining the code domain informationcorresponding to the measurement reference signal includes: acquiringthe code domain information of the measurement reference signalaccording to first information, where the first information includes atleast one of the following:

-   -   an ID of a measurement reference signal resource in which the        measurement reference signal is located; the number N of time        domain symbols included in a time unit in which the measurement        reference signal is located; a positive integer M; the number L        of time domain symbols occupied by the measurement reference        signal in one time unit; index information l₂ of a time domain        symbol, in which the measurement reference signal is located, in        N time domain symbols included in one time unit; index        information l₁ of a time domain symbol, in which the measurement        reference signal is located, in M preset time domain symbols;        index information l₀ of the measurement reference signal in the        L time domain symbols; a frame number of a frame in which the        measurement reference signal is located; the number B of time        units included in the frame in which the measurement reference        signal is located; a time unit index acquired according to a        subcarrier spacing of a BWP in which the measurement reference        signal is located; a random sequence with a length of D; a        virtual cell number n_(ID) ^(SRS); a frequency domain repeated        sending parameter R corresponding to the measurement reference        signal; a sequence repetition parameter R5 corresponding to the        measurement reference signal; or F; where B, D, L, N, M and L        are positive integers.

M satisfies the following condition: M is less than or equal to N and isgreater than or equal to A, where A is the maximum number of time domainsymbols allowed to be occupied by the measurement reference signal inone time unit, or A is the number of time domain symbols occupied by themeasurement reference signal in one time unit.

The frequency domain repeated sending parameter R (the frequency domainresource includes a frequency domain physical resource block (PRB)and/or a frequency domain subcarrier) represents that the measurementreference signal hops once in frequency domain every R time domainsymbols; the sequence repetition parameter R5 represents that themeasurement reference signal hops once in sequence or sequence parameterevery R5 time domain symbols; the R time domain symbols or the R5 timedomain symbols include the measurement reference signal; and the F timedomain symbols include the measurement reference signal.

Example One

In this example of the present disclosure, an uplink measurementreference signal may be sent by using a time domain OCC, where the timedomain OCC is less than or equal to a frequency domain repeated sendingparameter R corresponding to the uplink measurement reference signal inone slot, where the frequency domain repeated sending parameter R of theuplink measurement reference signal represents that frequency domainresources occupied by the measurement reference signal on R time domainsymbols are the same, where the frequency domain resources include atleast one of the following resources: frequency domain PRBs, andsubcarriers in a PRB.

A base station notifies a terminal of the time domain OCC used by itsmeasurement reference signal. For example, one measurement referencesignal includes one port which may correspond to one OCC as shown inTable 1. Table 1 is a schematic table one according to Example 1.

TABLE 1 Measurement Reference Signal Port OCC Port 0 [1, 1, 1, 1] Port 1[1, −1, 1, −1] Port 2 [1, 1, −1, −1] Port 3 [1, −1, −1, 1]

In Table 1, different OCCs correspond to different ports. As shown inFIGS. 7 and 8, mapping from OCCs to time domain symbols is illustrated.FIG. 7 is a schematic diagram illustrating a mapping relationshipbetween a time domain OCC corresponding to a port 0 and time domainsymbols according to the present disclosure, and FIG. 7 illustratesmapping from an OCC of the port 0 to time domain symbols. FIG. 8 is aschematic diagram of a mapping relationship between a time domain OCCcorresponding to a port 1 and time domain symbols according to thepresent disclosure, and FIG. 8 illustrates mapping of OCCs from the port1 to time domain symbols. In this case, the measurement reference signalport index may be informed by signaling. For example, an SRS resource 1includes the port 0 and an SRS resource 2 includes port 1, and althoughboth SRS resource 1 and SRS resource 2 include one port, one of themcorresponds to the port 0 and the other corresponds to the port 1, wherethe SRS resource 1 and the SRS resource 2 may be SRS resources allocatedto different terminals. Four time domain symbols participating in thetime domain OCC in each of FIGS. 7 and 8 may be consecutive time domainsymbols, or inconsecutive time domain symbols, or time domain symbols inone slot, or time domain symbols in multiple slots.

In another implementation manner of this example, the base stationdirectly signals an OCC index, one SRS resource corresponds to one OCC,and multiple ports included in one SRS resource share one OCC, as shownin Table 2. Table 2 is a schematic table two according to Example 1.

TABLE 2 OCC Index OCC Index 0 [1, 1, 1, 1] Index 1 [1, −1, 1, −1] Index2 [1, 1, −1, −1] Index 3 [1, −1, −1, 1]

For example, both an SRS resource 3 and an SRS resource 4 are resourcesincluding four SRS ports, the SRS resource 3 corresponds to the OCCindex 0, the SRS resource 4 corresponds to the OCC index 1, and four SRSports in the SRS resource 3 share the time domain OCC [1, 1, 1, 1]. Inanother implementation manner of this example, all SRS ports included inall SRS resources in one SRS resource set share one time domain OCCindex. Of course, this example does not exclude that different SRS portsin one SRS resource use different time domain OCCs.

In the above-described manner of this example, the base station notifiesthe terminal of the time domain OCC index used by the SRS throughsignaling information. For example, the base station signals a portindex used by the SRS, or a time domain OCC index used by the SRS. Thebase station may further signal length information of the time domainOCC.

In another implementation manner of this example, the base station mayalso agree on a rule with the terminal, so that the terminal may obtainthe information described above through the agreed rule. For example,the terminal may obtain an OCC index (or a port index) used by theterminal through an SRS resource ID, for example, a code indexOCC_(index)=(SRSID)modeT of a time domain OCC, where SRSID is anidentifier (ID) of the SRS resource, and T is the total number ofavailable OCCs, or a length of the time domain OCC. Similarly, the timedomain OCC index may be obtained through an ID of an SRS resource groupor set in which the SRS resource is located, or an identity number ofthe terminal. For example, the time domain OCC index may be obtainedthrough a C-RNTI.

In the present application, the uplink measurement reference signal mayalso be referred to as the uplink sounding reference signal.

Example Two

In this example, a time domain OCC of an SRS has an association with anSRS sequence.

In one embodiment, the length of the time domain OCC of the SRS isassociated with whether the SRS sequence changes with the time domainsymbol, or whether the time domain OCC of the SRS is enabled isassociated with whether the SRS sequence changes with the time domainsymbol, or the length of the time domain OCC of the SRS is associatedwith whether an SRS sequence parameter changes with the time domainsymbol, where the SRS sequence parameter may be at least one of thefollowing parameters: a sequence group number, or a sequence number.

In one embodiment, the length of the time domain OCC of the SRS is 1,which may also be referred to that the time domain OCC of the SRS is notenabled. The length of the time domain OCC of the SRS is greater than 1,which may also be referred to that the time domain OCC of the SRS isenabled.

In a case where the length of the time domain OCC of the SRS is greaterthan 1, the sequence of the SRS is invariant in a time domain symbol inwhich the time domain OCC is located; in a case where the length of thetime domain OCC of the SRS is equal to 1, the sequence of the SRS isvariable in the time domain symbol in which the time domain OCC islocated; and/or

-   -   in a case where the length of the time domain OCC of the SRS is        greater than 1, the sequence group number of the SRS is        invariant in the time domain symbol in which the time domain OCC        is located; in a case where the length of the time domain OCC of        the SRS is equal to 1, the sequence group number of the SRS is        variable in the time domain symbol in which the time domain OCC        is located; and/or    -   in a case where the length of the time domain OCC of the SRS is        greater than 1, the sequence number of the SRS is invariant in        the time domain symbol in which the time domain OCC is located;        in a case where the length of the time domain OCC of the SRS is        equal to 1, the sequence number of the SRS is variable in the        time domain symbol in which the time domain OCC is located.

In one embodiment, the sequence r_(u,v) ^((α,δ))(n) of the SRS in the NRis acquired through the following formula.

$\begin{matrix}{{{r_{u,v}^{({\alpha,\delta})}(n)} = {e^{j\; {\alpha {({n + {\delta \frac{\varpi \mspace{11mu} {mod}\mspace{14mu} 2}{2}}})}}}{{\overset{\_}{r}}_{u,v}(n)}}},{0 \leq n < M_{sc}^{RS}}} & \left( {1\text{-}0} \right)\end{matrix}$

When the time domain OCC is adopted, a reference signal sent on the SRSis acquired through the following formula.

S _(u,v) ^((α,δ))(n,l)=w(l)r _(u,v) ^((α,δ))(n), 0≤n<M _(sc)^(RS)  (1-1)

In the above formula, M_(sc) ^(RS)=mN_(sc) ^(RB)/2^(δ) is the sequencelength of the SRS, m is the number of PRBs occupied by the SRS, δ is thetotal number of combs in the Interleaved Frequency Division MultipleAccess (IFDMA) manner, α is a cyclic shift parameter, ω belongs to {0,1} or is fixed to 0, and w(l) is an element of the time domain OCC onthe time domain symbol l, or is referred to as a phase scrambling factorof the time domain OOC on the time domain symbol l.

In one embodiment, in response to ω being fixed to 0, the formula (1-0)is equivalent to: r_(u,v) ^(α)(n)=e^(jαn) r _(u,v)(n), 0≤n<M_(sc) ^(RS).

In the present application, the sequence corresponding to the SRS is asymbol set to be transmitted by the SRS before the SRS is multiplied bythe time domain OCC. For example, multiple symbols to be transmitted bythe SRS on multiple resource elements (REs) occupied by the SRS ononetime domain symbol form the sequence, that is, r_(u,v) ^((α,δ))(n),n=0, 1, 2 . . . M_(SC) ^(RS) in the formula (1-1) forms a sequencecorresponding to the SRS.

In response to the sequence length M_(SC) ^(RS) of the SRS being greaterthan 2N_(SC) ^(NB) (N_(SC) ^(NB) is the number of subcarriers includedin one PRB, and for example, in LTE and NR, N_(SC) ^(NB) is 12),

${{{\overset{\_}{r}}_{u,v}(n)} = {x_{q}\left( {n\mspace{14mu} {mod}\mspace{14mu} N_{zc}^{RS}} \right)}},{n = 0},1,\ldots \mspace{14mu},{M_{SC}^{RS} - 1},{{x_{q}(m)} = e^{{- j}\frac{\pi \; {{qm}{({m + 1})}}}{N_{zc}^{RS}}}},{m = 0},1,\ldots \mspace{14mu},{N_{zc}^{RS} - 1},{{q = {\left\lfloor {\overset{\_}{q} + {1/2}} \right\rfloor + {v \times \left( {- 1} \right)^{\lfloor{2\overset{\_}{q}}\rfloor}}}};{and}}$$\overset{\_}{q} = {{N_{zc}^{RS}\left( {u + 1} \right)}/31.}$

In the above formulas, v is the sequence number and belongs to {0, 1},0≤α≤2π, and N_(zc) ^(RS) s a largest prime less than or equal to M_(SC)^(RS). In one embodiment, when the number of PRBs occupied by the SRS isless than 6, v is 0; otherwise, v may be 0 or 1.

In response to the sequence length M_(SC) ^(RS) of the SRS being lessthan or equal to 2N_(SC) ^(NB),

r _(u,v)(n)=e ^(jφ(n)π/4) , n=0, 1, . . . , M _(SC) ^(RS)−1.

In the above formula, φ(n) is obtained by searching a preset tableaccording to the sequence group number u.

The sequence group number u is obtained through the following formula.

$\begin{matrix}{u = {\left( {{f_{gh}\left( n_{s} \right)} + f_{ss}} \right){mod}\; 30}} & (1) \\{{f_{gh}\left( n_{s} \right)} = \left\{ \begin{matrix}0 & {{if}\mspace{14mu} {the}\mspace{14mu} {group}\mspace{14mu} {hop}\mspace{14mu} {is}\mspace{14mu} {not}\mspace{14mu} {enabled}} \\{\left( {\sum_{i = 0}^{7}{{c\left( {{8{h{()}}} + i} \right)} \cdot 2^{i}}} \right){mod}\mspace{14mu} 30} & {{if}\mspace{14mu} {the}\mspace{14mu} {group}\mspace{14mu} {hop}\mspace{14mu} {is}\mspace{14mu} {enable}}\end{matrix} \right.} & (2)\end{matrix}$

In the above formulas, c(z) is the z-th value in a Pseudo-randomsequence. Once an initialization value c_(init) is given, a randomsequence can be generated. The initialization value in the sequencegeneration is

${c_{init} = \left\lfloor \frac{n_{ID}^{RS}}{30} \right\rfloor},$

f_(ss)=n_(ID) ^(RS) mod 30, where n_(ID) ^(RS) is a parameter configuredby the higher-layer or a physical cell identification number.

A length-31 Pseudo-random sequence is generated in the following manner.

c(n)=(x ₁(n+N _(C))+x ₂(n+N _(C)))mod 2

x ₁(n+31)=(x ₁(n+3)+x ₁(n))mod 2

x ₂(n+31)=(x ₂(n+3)+x ₂(n+2)+x ₂(n+1)+x ₂(n))mod 2

n=0, 1, . . . , M_(PN)−1, N_(C)=1600, x₁(0)=1, x₁(n)=0, n=1, 2, . . . ,30, and c_(init)=Σ_(i=0) ³⁰x₂(i)·2^(i).

In formula (2), h( ) is a function with respect to the time parameter,and therefore, the sequence group number corresponding to onemeasurement reference signal port or one measurement reference signalresource will change with the time domain symbol.

However, when the SRS uses the time domain OCC to be orthogonal, the twoSRS resources 1 and 2 having the partial frequency domain overlappingare orthogonal to each other. FIG. 9 is a schematic diagram illustratingorthogonalization of two SRS resources partially overlapping infrequency domain via a time domain OCC according to the presentdisclosure. As shown in FIG. 9, in order to make the port in the SRSresource 1 and the port in the SRS resource 2 orthogonal to each other,the time domain OCC may be used. Since the sequences corresponding tothe overlapping portion of the SRS resource 1 and the SRS resource 2 aredifferent, in this case, in order to be orthogonal, the SRS resource 1uses the same sequence on two time domain symbols in which the timedomain OCC is located, and similarly, the SRS resource 2 uses the samesequence on two time domain symbols in which the time domain OCC islocated, such that the sequence group number u does not change on thetime domain symbols in which the time domain OCC is located.

In other words, the h( ) function does not include the time domainsymbol index, or multiple time domain symbols of the time domain symbolsin which the time domain OCC is located have the same value in the h( )function.

Therefore, the base station and the terminal can agree that theacquisition parameter of h( ) does not include the time domain symbolindex when the length of the time domain OCC is greater than 1, and theacquisition parameter of h( ) includes the time domain symbol index whenthe length of the time domain OCC is 1; or the base station and theterminal agree that the hopping of the sequence group number u over timeis not enabled when the length of the time domain OCC is greater than 1,and the hopping of the sequence group number u over time is enabled whenthe length of the time domain OCC is 1; or the base station and theterminal agree that multiple time domain symbols in which the timedomain OCC is located take the same value in h( ) when the length of thetime domain OCC is greater than 1, and multiple time domain symbols inwhich the time domain OCC is located may take different values in h( )when the length of the time domain OCC is equal to 1.

Similarly, for example, the sequence number v is obtained through thefollowing formula:

$v = \left\{ {\begin{matrix}{0,{{sequence}\mspace{14mu} {number}\mspace{14mu} {hoppoing}\mspace{14mu} {is}\mspace{14mu} {not}\mspace{14mu} {enabled}}} \\{{c\left( z_{1} \right)},{{sequence}\mspace{14mu} {number}\mspace{14mu} {hopping}\mspace{14mu} {is}\mspace{14mu} {enabled}}}\end{matrix}.} \right.$

When the hopping of the sequence number is enabled, v=c(z₁), and thebase station and the terminal may agree that the acquisition parameterof z₁ does not include the time domain symbol index when the length ofthe time domain OCC is greater than 1, and the acquisition parameter ofz₁ includes the time domain symbol index when the length of the timedomain OCC is equal to 1; or the base station and the terminal may agreethat the hopping of the sequence number v over time is not enabled whenthe length of the time domain OCC is greater than 1, and the hopping ofthe sequence number v over time is enabled when the length of the timedomain OCC is equal to 1; or the base station and the terminal agreethat multiple time domain symbols in which the time domain OCC islocated take the same value in z₁ when the length of the time domain OCCis greater than 1, and multiple time domain symbols in which the timedomain OCC is located may take different values in z₁ when the length ofthe time domain OCC is equal to 1.

In the above implementation manner, the length of the time domain OCC isrelated to the sequence, or a code set of the time domain OCC may berelated to the sequence. For example, the terminal and the base stationagree that in response to the time domain OCC belonging to a set 1={(1,1, 1, 1, 1)}, the acquisition parameter of h( ) includes the time domainsymbol index, or the hopping of the sequence group number u over time isenabled, or four time domain symbols in which the time domain OCC islocated may take different values in h( ); in response to the timedomain OCC belonging to a set 2={(1, −1, 1, −1), (1, 1, −1, −1), (1, −1,−1, 1)}, the acquisition parameter of h( ) does not include the timedomain symbol index, or the hopping of the sequence group number u overtime is not enabled, or four time domain symbols in which the timedomain OCC is located may take the same value in h( ).

Similarly, the code set of the time domain OCC may also be related tothe sequence number v. For example, the terminal and the base stationagree that in response to the time domain OCC belonging to the set1={(1, 1, 1, 1, 1)}, the acquisition parameter of z₁ includes the timedomain symbol index, or the hopping of the sequence number v over timeis enabled, or four time domain symbols in which the time domain OCC islocated may take different values in z₁; in response to the time domainOCC belonging to the set 2={(1, −1, 1, −1), (1, 1, −1, −1), (1, −1, −1,1)}, the acquisition parameter of z₁ does not include the time domainsymbol index, or the hopping of the sequence number v over time is notenabled, or four time domain symbols in which the time domain OCC islocated may take the same value in z₁.

The division of the code set 1 of the time domain OCC and the code set 2of the time domain OCC is only an example, and other division mannersare not excluded. In a word, the time domain code set has an associationwith a generation mode of the sequence, or the time domain code set hasan association with a parameter of the sequence.

Example Three

In this example, when the uplink reference signal uses the time domainOCC, the length of the time domain OCC satisfies at least one of thefollowing features.

The feature one is as follows: a length of a time domain OCCcorresponding to the measurement reference signal is less than or equalto a frequency domain repeated sending parameter R corresponding to themeasurement reference signal, where the frequency domain repeatedsending parameter R is the number of time domain symbols included in aunit of frequency domain hopping of the measurement reference signal inone unit. FIG. 10 is a schematic diagram illustrating a frequency domainrepeated sending parameter R of an SRS being 2 according to the presentdisclosure. As shown in FIG. 10, one measurement reference signal portoccupies four symbols in one slot. Frequency domain resources occupiedby the SRS in the first two time domain symbols are the same, andfrequency domain locations occupied by the SRS in the last two timedomain symbols are the same. Frequency domains occupied by the SRS inthe first two time domain symbols are different from frequency domainsoccupied by the SRS in the last two time domain symbols, for example,the SRS occupies different PRBs, but combs occupied in IFDMA may be thesame. In FIG. 10, the frequency domain repeated sending parameter Rrepresents that frequency domain resources (frequency domain resourcesinclude frequency domain PRBs and frequency domain subcarriers) occupiedby the measurement reference signal on R time domain symbols in one timeunit are not changed, and may also represent that frequency domainhopping is performed once after the measurement reference signal is sentevery R time domain symbols (that is, the measurement reference signalis sent on R time domain symbols), where the R time domain symbols maybe located in different slots or may be located in the same time unit.The frequency domain resources include at least one of followingresources: PRBs, subcarriers in the PRB, or subcarriers.

The feature two is as follows: the length of the time domain OCCcorresponding to the measurement reference signal is less than or equalto a sequence repetition parameter R5 of the measurement referencesignal, where the sequence of the uplink reference signal and/or thesequence parameter of the uplink reference signal is invariant over theR5 time domain symbols. FIG. 11 is a schematic diagram illustrating asequence repetition parameter R5 of an SRS being 2 according to thepresent disclosure. As shown in FIG. 11, one SRS port occupies four timedomain symbols in one slot. Sequences occupied by the SSRS in the firsttwo time domain symbols are the same, that is, symbols used by the SRSon the same subcarriers in the first two time domain symbols are thesame (for example, symbols of the SRS on a first subcarrier before thetime domain OCC are a1, that is, r_(u,v) ^((α,δ))(n) on the RE in theformula (1-0) is a1). Sequences used by the SRS in the last two timedomain symbols are the same, that is, symbols used by the SRS on thesame subcarriers in the last two time domain symbols are the same.Therefore, the sequence repetition parameter R5 of the SRS is equal to2, so that the time domain OCC can only be mapped on the first two timedomain symbols, or mapped on the last two time domain symbols, and thelength of the time domain OCC is less than or equal to 2. FIG. 12 is aschematic diagram illustrating a sequence repetition parameter R5 of anSRS being 4 according to the present disclosure. As shown in FIG. 12,one SRS port occupies four symbols in one slot. Sequences occupied bythe SRS in the four time domain symbols are the same, that is, thesymbols used by the SRS on the same subcarriers in the four time domainsymbols before the time domain OCC are the same. Therefore, the sequencerepetition parameter R5 of the SRS is equal to 4, and the length of thetime domain OCC may be less than or equal to 4. In FIGS. 11 to 12, oneSRS port occupies four time domain symbols in one slot. In this example,the acquisition of the sequence repetition parameter R5 of the SRS mayalso be cross-slot. FIG. 13 is a schematic diagram illustrating asequence repetition parameter R5 of an SRS being 4 and one sequencerepetition sending unit including time domain symbols in more than oneslot according to the present disclosure, that is, as shown in FIG. 13,the sequence repetition parameter R5 of the SRS is 4, and the sequencerepetition parameter R5 may also be referred to as the number of timedomain symbols for sequence hopping. The sequence repetition parameterR5 may also be referred to as a relationship between the SRS sequenceand the time domain symbol. In one embodiment, the sequence repetitionparameter R5 is also referred to as a sequence repetition sendingparameter.

The feature three is as follows: the length of the time domain OCCincludes a length 1. The length of the time domain OCC being 1 may alsobe referred to that the time domain OCC is not enabled. In the presentapplication, the length of the time domain OCC belongs to {1, 2, 4}, orthe length of the time domain OCC belongs to {1, 2, 4, 8}.

The feature four is as follows: the length of the time domain OCC has anassociation with the sequence parameter of the measurement referencesignal. For example, when the length of the time domain OCC is greaterthan 1, sequences corresponding to one SRS port on R1 time domainsymbols occupied in one time unit are the same, and/or when the lengthof the time domain OCC is greater than 1, sequence group numberscorresponding to one SRS port on R1 time domain symbols occupied in onetime unit are the same (the sequence group number is u described inExample 1). When the length of the domain OCC is greater than 1,sequence numbers corresponding to one SRS port on R1 time domain symbolsoccupied in one time unit are the same (the sequence number is vdescribed in Example 1). When sequences corresponding to one SRS port onR1 time domain symbols occupied in one time unit are different, thelength of the time domain OCC corresponding to the measurement referencesignal port is 1; when sequence group numbers corresponding to one SRSport on R1 time domain symbols occupied in one time unit are different,the length of the time domain OCC corresponding to the measurementreference signal port is 1; and when sequence numbers corresponding toone SRS port on R1 time domain symbols occupied in one time unit aredifferent, the length of the time domain OCC corresponding to themeasurement reference signal port is 1.

R1 at least satisfies one of the following features: R1 is less than orequal to R, R1 is the length of the time domain OCC, or R1 is less thanor equal to N, where N is the number of time domain symbols included bythe measurement reference signal in one time unit.

In the above example, the R1 time domain symbols are in one time unit,for example, in one slot. Of course, this example does not exclude acase that the R1 time domain symbols may include time domain symbols inmultiple time units, for example, the R1 time domain symbols includetime domain symbols in more than one slot.

In this example, Features one to four are described with the uplinkmeasurement reference signal as an example. Of course, other uplinkreference signals may also apply to one or more features of Features oneto four, for example, the uplink demodulation reference signal, theuplink phase tracking reference signal or the uplink random channelsequence (preamble).

Example Four

In this example, the base station sends signaling information to theterminal, where the signaling information includes at least one of thefollowing: information about a correspondence between the sequence andthe time domain symbol, or a time domain OCC corresponding to a timedomain symbol set, which may also be referred to as a phase scramblingfactor corresponding to the time domain symbol in the time domain symbolset.

The information about the correspondence between the sequence and thetime domain symbol includes at least one of the following: informationabout whether the sequence parameter changes on R2 time domain symbolsin one time unit; information about whether the sequence changes on R2time domain symbols in one time unit; the sequence hopping once every R3time domain symbols (that is, the sequence hops once after R3 timedomain symbols occupied by the measurement reference signal); and thesequence parameter hopping once every R3 time domain symbols (that is,the sequence parameter hops once after R3 time domain symbols occupiedby the measurement reference signal); where the sequence parameter isused for generating the sequence, and for example, the sequenceparameter includes at least one of the following parameters: a sequencegroup number (for example, the parameter u described in Example one), ora sequence number (for example, the parameter v described in Exampleone).

In a word, the sequence parameters hops once after R3 time domainsymbols occupied by the channel or signal, where the R3 time domainsymbols may be in one time unit, or in multiple time units, where onetime unit may be one slot, or one subframe, and of course other timeunits are not excluded. In one embodiment, the time domain OCCcorresponding to the time domain symbol set may also be referred to as aphase scrambling factor corresponding to the time domain symbol in thetime domain symbol set.

In one embodiment, R2 or R3 satisfy at least one of the followingfeatures: R2 or R3 is less than or equal to R, R2 or R3 is less than orequal to a length of a time domain OCC corresponding to a channel or asignal, or R2 or R3 is less than or equal to N, where N is the number oftime domain symbols included by the channel or the signal in one timeunit, and the channel or the signal is a channel or a signalcorresponding to the signaling information. In one embodiment, R2 and R3are also referred to as the sequence repetition sending parameter, orthe sequence hopping parameter, or other equivalent names.

The sequence is transmitted on the following channel or signal: acontrol channel, a data channel, a measurement reference signal, or ademodulation reference signal. The orthogonalization between the SRS andthe control channel can be achieved through using the time domain OCCsuch that time domain OCC information used by the control channel andthe time domain OCC used by the SRS are notified. Similarly, the timedomain OCC index used by the data channel can be notified, or the timedomain OCC index used by the demodulation reference signal can benotified.

In one embodiment, a signal transmitted on the time domain symbol in thetime domain symbol set is transmitted by the channel or signalcorresponding to the signaling information after the signal ismultiplied by the time domain OCC corresponding to the time domainsymbol in the time domain symbol set.

Alternatively, when signals transmitted on multiple time domain symbolsin the time domain symbol set by the channel or signal corresponding tothe signaling information are the same, the signals are transmittedafter being multiplied by the time domain OCC. For example, theorthogonalization between the uplink control channel and the SRS on thesame frequency domain resource can be achieved through the time domainOCC, but since the sequences used by the uplink control channel and theSRS are different, sending sequences corresponding to the uplink controlchannel on the time domain symbol set corresponding to the time domainOCC are the same, and sending sequences corresponding to the sequenceused by the SRS on the time domain symbol set corresponding to the timedomain OCC are also the same.

In this example or the present application, the sequence consists of asymbol of information sent on the channel or signal before theinformation is multiplied by the time domain OCC. For example, multiplesymbols on multiple REs on one time domain symbol before beingmultiplied by the OCC form one sequence.

Example Five

In this example, the code domain information of the SRS hops once everyF time domain symbols, where the code domain information includes atleast one of the following: a time domain OCC index of the SRS, asequence parameter, or a port index, where F is a positive integergreater than or equal to 1. The F time domain symbols include the SRS,that is, time domain symbols which do not include the SRS are notcounted in the F. The sequence parameter is used for generating thesequence, and for example, when the SRS uses a Zadoff-Chu (ZC) sequencein the formula (1-1) or the formula (1-0) or a preset sequence, thesequence parameter includes at least one of the following parameters: asequence group number u, a sequence number v, and a cyclic shift n_(SRS)^(cs,i).

In one embodiment, the code domain information of the measurementreference signal is acquired according to first information, where thefirst information includes at least one of the following: an ID of ameasurement reference signal resource in which the measurement referencesignal is located, for example, Portindex=(SRSID)modeT, where SRSIDrepresents the ID of the SRS resource in which the SRS is located; thenumber N of time domain symbols included in a time unit in which themeasurement reference signal is located (for example, one slot includes14 time domain symbols, that is, N=14, if one slot includes 12 timedomain symbols, N=12, and of course, cases that one slot includes othernumbers of time domain symbols are not excluded in this example); apositive integer M; the number L of time domain symbols occupied by themeasurement reference signal in one time unit, where for example, L isthe number of time domain symbols occupied by the measurement referencesignal in one slot, and belongs to {1, 2, 4}; index information l₂ of atime domain symbol, in which the measurement reference signal islocated, in N time domain symbols included in one time unit; indexinformation l₁ of a time domain symbol, in which the measurementreference signal is located, in M preset time domain symbols; indexinformation l₀ of the measurement reference signal in the L time domainsymbols; a frame number of a frame in which the measurement referencesignal is located; the number B of time units included in the frame inwhich the measurement reference signal is located; a time unit indexacquired according to a subcarrier spacing of a BWP in which themeasurement reference signal is located; a random sequence with a lengthof D; a virtual cell number n_(ID) ^(SRS); a frequency domain repeatedsending parameter R corresponding to the measurement reference signal; asequence repetition parameter R5 corresponding to the measurementreference signal; or F.

In one embodiment, the index information l_(i), i=1,2 may be obtainedthrough the following formula: l_(i)=l_(i) ^(start)+l′, where l₂^(start) is index information of a starting time domain symbol, occupiedby the measurement reference signal in a time unit, in the time unit, l₁^(start) is index information of the starting time domain symboloccupied by the measurement reference symbol in the preset M time domainsymbols, and l′=0, 1, . . . , L−1 is index information of the timedomain symbol occupied by the measurement reference signal in the L timedomain symbols. For example, when one SRS port or one SRS resourceoccupies four time domain symbols whose indexes are {9, 10, 11, 12} inone slot, l₂ ^(start) is 9, and l₁ ^(start) is 1, where it is assumedthat the M preset time domain symbols are time domain symbols whoseindexes are {8, 9, 10, 11, 12, 13} in one slot, that is, the M presettime domain symbols are the last six time domain symbols in one slot. Inthis case, l′=0, 1, 2, 3.

M satisfies the following condition: M is less than or equal to N and isgreater than or equal to A, where A is the maximum number of time domainsymbols allowed to be occupied by the measurement reference signal inone time unit. For example, the SRS in NR may occupy last six timedomain symbols in one slot, that is, A is 6 or M is 6, or A is thenumber of time domain symbols occupied by the measurement referencesignal in one time unit. For example, time domain symbols occupied byone SRS resource in one slot belong to {1, 2, 4}, that is, A belongs to{1, 2, 4}. The frequency domain repeated sending parameter R representsthat frequency domain resources occupied by the measurement referencesignal on R time domain symbols in one time unit are not changed, wherethe frequency domain resources include at least one of the following:PRB resources, or REs (also referred to as subcarriers) in PRBs. Forexample, PRBs occupied by the measurement reference signal on R timedomain symbols are the same, but subcarriers in PRBs occupied by themeasurement reference signal may be different; or PRBs occupied by themeasurement reference signal on R time domain symbols are the same, andsubcarriers in PRBs occupied by the measurement reference signal mayalso be the same. Alternatively, the frequency domain repeated sendingparameter R represents that frequency domain resources corresponding tothe measurement reference signal hop after R time domain symbolsoccupied by the measurement reference signal, where the R time domainsymbols may be located in one slot, or may be located in multiple slots.

In one embodiment, the time domain OCC index or the port index used bythe SRS is acquired through the following formulas.

${Portindex} = {\left( {w_{0} + {\sum\limits_{i = 0}^{D_{1} - 1}{{c\left( {{D_{1}{g(X)}} + i} \right)}2^{i}}}} \right){mod}\mspace{14mu} T}$${Portindex} = {\left( {w_{0} + {\sum\limits_{i = 0}^{D_{1} - 1}{{c\left( {{D_{1}\left\lfloor {{g(X)}/F} \right\rfloor} + i} \right)}2^{i}}}} \right){mod}\mspace{14mu} T}$

In the above formulas, g(X) is a function with respect to X; X is thefirst information; Portindex represents the port index corresponding tothe measurement reference signal or the time domain OCC corresponding tothe measurement reference signal; T is one of the following information:the length of the time domain OCC, the total number of time domain OCCsavailable to the SRS, the total number of different ports of the SRS,the frequency domain repeated sending parameter R of the measurementreference signal, and the sequence repetition parameter R5 of themeasurement reference signal; c(z) represents the z-th value of arandomized sequence; w₀ϵ{0, 1, . . . T−1} is a predetermined value, orw₀ is included in the received signaling information; D₁ is an integergreater than or equal to 1, for example D₁=8; F is R, or is R5, or isthe smaller of R and R5.

Similarly, the cyclic shift parameter (the cyclic shift parameter is αin formula (1-1) or formula (1-0), for example,

$\alpha_{i} = {2\pi \frac{n_{SRS}^{{cs},i}}{n_{SRS}^{{cs},\max}}}$

of an i-th measurement reference signal port) of the SRS may alsochanges over time. For example, the cyclic shift n_(SRS) ^(cs,i)corresponding to the SRS is acquired through one of the followingformulas.

$\begin{matrix}{{n_{SRS}^{{cs},i} = {\left( {n_{SRS}^{cs} + \frac{n_{SRS}^{{cs},\max}p_{i}}{N_{ap}^{SRS}} + {\sum\limits_{i = 0}^{D_{2} - 1}\left( {{c\left( {{D_{2}{g(X)}} + i} \right)}2^{i}} \right)}} \right){mod}\mspace{14mu} n_{SRS}^{{cs},\max}}},{i = 0},1,\ldots \mspace{14mu},{N_{ap}^{SRS} - 1}} & \left( {3\text{-}1} \right) \\{{n_{SRS}^{{cs},i} = {\left( {n_{SRS}^{cs} + \frac{n_{SRS}^{{cs},\max}p_{i}}{N_{ap}^{SRS}} + {\sum\limits_{i = 0}^{D_{2} - 1}\left( {{c\left( {{D_{2}\left\lfloor {{g(X)}/F} \right\rfloor} + i} \right)}2^{i}} \right)}} \right){mod}\mspace{14mu} n_{SRS}^{{cs},\max}}},{i = 0},1,\ldots \mspace{14mu},{N_{ap}^{SRS} - 1}} & \left( {3\text{-}2} \right)\end{matrix}$

The sequence group number u is acquired through one of the followingformulas.

$u = {\left( {{{f_{gh}\left( \left( {\sum\limits_{i = 0}^{D_{3} - 1}{{c\left( {{D_{3}{g(X)}} + i} \right)}2^{i}}} \right) \right)}{mod}\mspace{9mu} C} + f_{ss}} \right){mod}\mspace{9mu} C}$$u = {\left( {{{f_{gh}\ \left( \left( {\sum\limits_{i = 0}^{D_{3} - 1}{{c\left( {{D_{3}\left\lfloor {{g(X)}/F} \right\rfloor} + i} \right)}2^{i}}} \right) \right)}{mod}\mspace{9mu} C} + f_{ss}} \right){mod}\mspace{9mu} C}$

The sequence number v is acquired through one of the following formulas.

v=c(g(X))

v=c(└g(X)/F┘)

In the above formulas, g(X) is a function with respect to X; X is thefirst information; N_(ap) ^(SRS) is the number of measurement referencesignal ports included in one SRS resource; n_(SRS) ^(cs,max) is anagreed value, represents the maximum number of cyclic shifts or thetotal number of available different cyclic shifts, and belongs to {8,12} or {8, 24}; p_(i)ϵ{0, 1, . . . N_(ap) ^(SRS)}; and c(z) is the z-thvalue of one randomized sequence; n_(SRS) ^(cs)ϵ{0, 1, . . . n_(SRS)^(cs,max)−1} is a predetermined value, or n_(SRS) ^(cs) is included inthe received signaling information; D₂ is an integer greater than orequal to 1; C is the total number of sequence groups, for example, 30;and f_(ss) is acquired according to the agreed rule and/or the parameterincluded in received signaling information, for example, f_(ss)=n_(ID)^(SRS) mod C.

For example, c(z) is a PN sequence, whose initial value is a functionwith respect to n_(ID) ^(SRS).

In one embodiment, the g(X) is one of the following formulas.

g(l ₁ ,M,n _(s))=l ₁ +n _(s) *M

g(l ₁ ,M,n _(s) ,n _(f))=l ₁ +n _(s) *M+B*n′ _(f) *M

g(l ₂ ,N,n _(s))=l ₂ +n _(s) *N

g(l ₂ ,N,n _(s) ,n _(f))=l ₂ +n _(s) *N+B*n′ _(f) *N

g(l ₀ ,L,n _(s))=l ₀ +n _(s) *L

g(l ₀ ,N,n _(s) ,n _(f))=l ₀ +n _(s) *N+B*n′ _(f) *N

g(l ₁ ,M,n _(s) ,F)=└l ₁ /F┘+n _(s) *M/F

g(l ₁ ,M,n _(s) ,n _(f) ,F)=└l ₁ /F┘+(n _(s) *M+B*n′ _(f) *M)/F

g(l ₂ ,N,n _(s) ,F)=└l ₂ /F┘+n _(s) *N/F

g(l ₂ ,N,n _(s) ,n _(f) ,r)=└l ₂ /r┘+(n _(s) *N+B*n′ _(f) *N)/r

g(l ₀ ,N,n _(s) ,n _(f) ,F)=└l ₀ /F┘+(n _(s) *N+B*n′ _(f) *N)/F

In the above formulas, n′_(f)=n_(f) or n′_(f)=n_(f) mod(E), n_(f) is aframe number of a frame in which the reference signal is located, and Eis a predetermined value.

Example Six

In this example, the terminal determines a parameter of a measurementreference signal according to an agreed restriction condition, andtransmits the measurement reference signal using the parameter.

In one embodiment, the parameter is a frequency hopping parameter of theSRS.

In one embodiment, the SRS is a measurement reference signal triggeredby physical layer dynamic signaling, and is, for example, an aperiodicSRS.

In one embodiment, the predetermined restriction condition is at leastone of the following conditions.

The condition one is as follows: the frequency domain resources occupiedby the measurement reference signal in one slot are consecutive. FIG. 14is a schematic diagram illustrating a frequency domain location occupiedby an SRS in one slot being a union set of frequency domain locationsoccupied by the SRS in multiple time domain symbols in one slotaccording to the present disclosure. As shown in FIG. 14, one SRSresource occupies four time domain symbols in one slot. Frequency domainresources occupied in respective time domain symbols are different. Forexample, frequency domain PRBs occupied in respective time domainsymbols are different. Thus, the frequency domain resources occupied bythe SRS in one slot are a union set of frequency domain resourcesoccupied by the SRS in four time domain symbols. As shown in FIG. 14,this restriction condition is that frequency domain resources occupiedby the SRS in one slot are consecutive, no inconsecutive frequency bandexists in the frequency domain resources, and the frequency domainresources take PRBs as a unit.

The condition two is as follows: frequency domain subcarriers occupiedby the measurement reference signal in one time unit are evenlydistributed on the frequency domain resources occupied by themeasurement reference signal in one time unit.

The condition three is as follows: frequency domain resources occupiedby the measurement reference signal in one time unit are a frequencyhopping bandwidth, where the frequency hopping bandwidth is determinedthrough the parameter b_(hop). FIG. 15a is a structural diagramillustrating one bandwidth in third-level bandwidths in an SRS treestructure according to the present disclosure. As shown in FIG. 15a ,the bandwidth of the SRS is represented by a tree-like structure, or atree is referred to as a multilevel bandwidth structure. In the treestructure, one n-th level bandwidth includes one or more (n+1)-th levelbandwidths. As shown in FIG. 15a , the bandwidth at an upper levelincludes two bandwidths at a lower level. As shown in FIG. 15a , for abandwidth represented by the shadow part in the figure, correspondingbandwidth indexes in bandwidths of respective levels of b=0, 1, 2, 3 are0, 1, 1, 0, respectively. FIG. 15b is a structural diagram illustratingone bandwidth in second-level bandwidths in an SRS tree structureaccording to the present disclosure. For one bandwidth represented bythe shadow part in FIG. 15b , corresponding bandwidth indexes inbandwidths of respective levels of b=0, 1, 2 are 0, 0, 1, respectively.The frequency hopping bandwidth parameter b_(hop) is used forrepresenting a frequency domain range of frequency hopping of the SRS,that is, the union set of the frequency domain locations occupied by theSRS in each time domain symbol belongs to one bandwidth of b_(hop)-levelbandwidths. Alternatively, the frequency hopping bandwidth level set ofthe SRS obtained for the frequency hopping bandwidth parameter b_(hop)may also be referred to as {b_(hop)+1, b_(hop)+2, . . . , B_(SRS)}. FIG.16a is a schematic diagram illustrating a frequency hopping bandwidthlevel b_(hop)=1 according to the present disclosure, and FIG. 16a is aschematic diagram illustrating a frequency hopping bandwidth levelb_(hop)=2 according to the present disclosure.

The condition four is as follows: frequency domain resources occupied bythe measurement reference signal in one time unit are a BWP.

The condition five is as follows: frequency domain resources occupied bythe measurement reference signal in one time unit are a maximumbandwidth in the multilevel bandwidth structure. For example, frequencydomain resources occupied by the measurement reference signal in oneslot is one bandwidth determined through m_(SRS,0), where one bandwidthcorresponding to m_(SRS,0) is as shown in FIG. 16a or FIG. 16b , or maybe a bandwidth corresponding to the maximum bandwidth in the treestructure.

The condition six is as follows: a frequency hopping bandwidth level ofthe measurement reference signal is an agreed value, for example,b_(hop)=0 corresponding to an aperiodic measurement reference signal.

The condition six is as follows: the parameter of the measurementreference signal satisfies the following formula:

${{\sum\limits_{b \in b_{hopA}}N_{b}} = {{\frac{N_{s}}{R}\mspace{14mu} {or}\mspace{14mu} {\sum\limits_{b \in b_{hopA}}N_{b}}} < \frac{N_{s}}{R}}},$

where b is bandwidth level information in the multilevel bandwidthstructure; b_(hopA) is a frequency hopping bandwidth level set, that is,in the tree structure, the bandwidth index of the SRS changes over timein a bandwidth level belonging to b_(hopA), and does not change overtime in a bandwidth level which does not belong to b_(hopA); N_(s) isthe number of time domain symbols occupied by the measurement referencesignal in one time unit; R is the frequency domain repeated sendingparameter of the measurement reference signal. The multilevel bandwidthstructure includes multiple bandwidth levels, one bandwidth in (b−1)-thlevel bandwidths includes N_(b) bandwidths in b-th level bandwidths. Asshown in FIGS. 16a and 16b , N₀=1, N₁=2, N₂=2, N₃=2. The bandwidth indexoccupied by the measurement reference signal in a frequency hoppingbandwidth level changes over time. In one embodiment, the frequencydomain staring location k₀ occupied by the SRS may be obtained throughthe following formula:

${k_{0} = {{\overset{\_}{k}}_{0} + {\sum\limits_{b = 0}^{B_{SRS}}{K_{TC}M_{{sc},b}^{SRS}n_{b}}}}},$

where k ₀=n_(shift)N_(sc) ^(RB)+k_(TC), n_(shift) is a parameterconfigured by a higher layer, k_(TC) is an index of a comb in which theSRS is located when the SRS is transmitted in an IFDMA manner, k_(TC) isthe total number of combs of the SRS when the SRS is transmitted in anIFDMA manner.

$n_{b} = \left\{ {{\begin{matrix}{\left\lfloor {4{n_{RRC}/m_{{SRS},b}}} \right\rfloor {mod}\mspace{14mu} N_{b}} & {b \notin b_{hopA}} \\{\left\{ {{F_{b}\left( n_{SRS} \right)} + \left\lfloor {4{n_{RRC}/m_{{SRS},b}}} \right\rfloor} \right\} {mod}\mspace{14mu} N_{b}} & {otherwise}\end{matrix}{F_{b}\left( n_{SRS} \right)}} = \left\{ {{\begin{matrix}{{\left( {N_{b}/2} \right)\left\lfloor \frac{n_{SRS}\mspace{11mu} {mod}\mspace{14mu} {\prod_{{b^{\prime} \in b_{hopA}},{b^{\prime} \leq b}}^{b}N_{b^{\prime}}}}{\prod_{{b^{\prime} \in b_{hopA}},{b^{\prime} < b}}N_{b^{\prime}}} \right\rfloor} + \left\lfloor \frac{n_{SRS}\mspace{11mu} {mod}\mspace{14mu} {\prod_{{b^{\prime} \in b_{hopA}},{b^{\prime} \leq b}}^{b}N_{b^{\prime}}}}{2{\prod_{{b^{\prime} \in b_{hopA}},{b^{\prime} < b}}N_{b^{\prime}}}} \right\rfloor} & {{if}\mspace{14mu} N_{b}\mspace{14mu} {even}} \\{\left\lfloor {N_{b}/2} \right\rfloor \left\lfloor {n_{SRS}/{\prod_{{b^{\prime} \in b_{hopA}},{b^{\prime} < b}}N_{b^{\prime}}}} \right\rfloor} & {{if}\mspace{14mu} N_{b}\mspace{14mu} {odd}}\end{matrix}n_{SRS}} = {{\left( \frac{{N_{slot}^{{frame},\mu}n_{f}} + n_{s,f}^{\mu} - T_{offset}}{T_{SRS}} \right) \cdot \left( \frac{N_{symb}^{SRS}}{R} \right)} + \left\lfloor \frac{l^{\prime}}{R} \right\rfloor}} \right.} \right.$

It can be seen from the above formulas that when the bandwidth levelbelongs to b_(hopA), the bandwidth index n_(b) corresponding to the SRSin this bandwidth level changes over time; and when the bandwidth leveldoes not belong to b_(hopA), the bandwidth index n_(b) corresponding tothe SRS in this bandwidth level does not change over time, where n_(RRC)is a parameter configured by a higher layer.

In one embodiment, when N_(b) is equal to 1, the bandwidth index n_(b)does not change over time, which may be an exception of the bandwidthindex n_(b) changing over time. In one embodiment, when the frequencyhopping bandwidth is {b_(hop)+1, b_(hop)+2, . . . , B_(SRS)}, the aboveformulas may be updated to the following formulas.

$n_{b} = \left\{ {{\begin{matrix}{{\left\lfloor {4{n_{RRC}/m_{{SRS},b}}} \right\rfloor {mod}\ N_{b}}\ } & {b \leq b_{hop}} \\{\left\{ {{F_{b}\left( n_{SRS} \right)} + \left\lfloor {4{n_{RRC}/m_{{SRS},b}}}\  \right\rfloor} \right\} {mod}\mspace{14mu} N_{b}} & {otherwise}\end{matrix}{F_{b}\left( n_{SRS} \right)}} = \left\{ \begin{matrix}{{\left( {N_{b}/2} \right)\left\lfloor \frac{n_{SRS}\mspace{11mu} {mod}\mspace{14mu} {\prod_{b^{\prime} = b_{hop}}^{b}N_{b^{\prime}}}}{\prod_{b^{\prime} = b_{hopA}}^{b - 1}N_{b^{\prime}}} \right\rfloor} + \left\lfloor \frac{n_{SRS}\mspace{11mu} {mod}\mspace{14mu} {\prod_{b^{\prime} = b_{hop}}^{b}N_{b^{\prime}}}}{2{\prod_{b^{\prime} = b_{hop}}^{b - 1}N_{b^{\prime}}}} \right\rfloor} & {{if}\mspace{14mu} N_{b}\mspace{14mu} {even}} \\{\left\lfloor {N_{b}/2} \right\rfloor \left\lfloor {n_{SRS}/{\prod_{b^{\prime} = b_{hop}}^{b - 1}N_{b^{\prime}}}} \right\rfloor} & {{if}\mspace{14mu} N_{b}\mspace{14mu} {odd}}\end{matrix} \right.} \right.$

In the above formulas, when b′=b_(hop), N_(b′) is fixed to N_(b′)=1.

$n_{SRS} = {{\left( \frac{{N_{slot}^{{frame},\mu}n_{f}} + n_{s,f}^{\mu} - T_{offset}}{T_{SRS}} \right) \cdot \left( \frac{N_{symb}^{SRS}}{R} \right)} + \left\lfloor \frac{l^{\prime}}{R} \right\rfloor}$

Since the configuration parameter of the SRS is required to satisfy

${{\sum\limits_{b \in b_{hopA}}N_{b}} \leq \frac{N_{s}}{R}},$

only first parameter set information of the SRS may be configured, andsecond parameter set information may be obtained according to parameterconfiguration in the first parameter set information and a restrictioncondition

${\sum\limits_{b \in b_{hopA}}N_{b}} \leq {\frac{N_{s}}{R}.}$

For example, for five parameters (C_(SRS), B_(SRS), b_(hopA), N_(s), R),only part of parameters may be configured, and other parameters areobtained according to the configured parameters and

${\sum\limits_{b \in b_{hopA}}N_{b}} \leq {\frac{N_{s}}{R}.}$

For example, when (C_(SRS), B_(SRS), N_(s), R) are configured, theterminal further obtains b_(hopA) according to

${{\sum\limits_{b \in b_{hopA}}N_{b}} \leq \frac{N_{s}}{R}},$

or when (C_(SRS), B_(SRS), b_(hopA), R) are configured, the terminalfurther obtains N_(s) according to

${{\sum\limits_{b \in b_{hopA}}N_{b}} \leq \frac{N_{s}}{R}},$

or when (C_(SRS), b_(hopA), N_(s), R) are configured, the terminalfurther obtains B_(SRS) according to

${\sum\limits_{b \in b_{hopA}}N_{b}} \leq {\frac{N_{s}}{R}.}$

For the restriction condition

${{\sum\limits_{b \in b_{hopA}}N_{b}} \leq \frac{N_{s}}{R}},$

when b_(hopA)={b_(hop)+1, b_(hop)+2, . . . , B_(SRS)}, this restrictioncondition may be updated to:

${\underset{b = {b_{hop} + 1}}{\sum\limits^{B_{SRS}}}N_{b}} = {\frac{N_{s}}{R}\mspace{14mu} {or}}$${{\underset{b = {b_{hop} + 1}}{\sum\limits^{B_{SRS}}}N_{b}} \leq \frac{N_{s}}{R}},$

or this formula may be equivalent to

${\sum\limits_{b = b_{hop}}^{B_{SRS}}N_{b}} \leq {\frac{N_{s}}{R}.}$

For b=b_(hop), N_(b) is fixed to N_(b)=1, and in this case, only b_(hop)in parameters b_(hopA) needs to be known. In a word, the secondparameter set of the SRS is determined according to the first parameterset of the SRS and the predetermined restriction condition. The firstparameter set and/or the second parameter set satisfy at least one ofthe following: the first parameter set is included in received signalinginformation; the second parameter set is not included in the receivedsignaling information; the second parameter set includes bandwidthinformation occupied by the measurement reference signal on one timedomain symbol, for example, B_(SRS); and an intersection set of thefirst parameter set and the second parameter set is empty. The firstparameter set include one of the following parameters: an index of amultilevel bandwidth structure, for example, C_(SRS), where C_(SRS)represents one structure selected from multiple tree structures;bandwidth level information occupied by the measurement reference signalin one time unit, for example, B_(SRS); frequency hopping bandwidthlevel information of the measurement reference signal, for example,b_(hopA) or b_(hop) described above; information of the number of timedomain symbols occupied by the measurement reference signal in one timeunit, for example, N_(s); or a repeated sending parameter of themeasurement reference signal in one time unit, for example, R. Thesecond parameter set includes at least one of the following parameters:an index of a multilevel bandwidth structure, for example, C_(SRS),where C_(SRS) represents one structure selected from multiple treestructures; bandwidth level information occupied by the measurementreference signal on one time domain symbol, for example, b_(SRS);frequency hopping bandwidth level information of the measurementreference signal, for example, b_(hopA) or b_(hop) described above;information about the number of time domain symbols occupied by themeasurement reference signal in one time unit, for example, N_(S); and arepeated sending parameter of the measurement reference signal in onetime unit, for example R.

In one embodiment, if multiple second parameter values are obtainedaccording to the first parameter set of the SRS and the predeterminedrestriction condition, that is, multiple second parameter values satisfythe restriction condition, one of the second parameter values isselected from the multiple second parameter values according to anagreed rule. For example, a minimum value or a maximum value is selectedfrom the multiple second parameter values.

In one embodiment, the terminal and the base station agree that theparameter configuration of the SRS satisfies the agreed condition, orthe terminal is not expected to receive the SRS parameter configurationthat does not satisfy the agreed condition. If the terminal receives theSRS parameter configuration that does not satisfy the agreed condition,the terminal considers that the control information is an error, or theterminal does not send the SRS. Alternatively, if the terminal receivesthe SRS parameter configuration that does not satisfy the agreedrestriction condition, the terminal sends preset indication informationto a higher layer or the base station.

Example Seven

In this example, the total number of available cyclic shifts of the SRSwill be described. For example, for n_(SRS) ^(cs,max) in the formula(3-1) or (3-2), when the total number of combs of the IFDMA is four,n_(SRS) ^(cs,max)=12; when the total number of combs of the IFDMA istwo, n_(SRS) ^(cs,max)=24; or when the total number of combs of theIFDMA is two, n_(SRS) ^(cs,max) belongs to {8, 24}, where {8, 24} areobtained through signaling information or the agreed rule. The totalnumber of combs of the IFDMA is 2^(δ), where δ is 2^(δ) in a SRS lengthdetermination parameter M_(sc) ^(RS)=mN_(sc) ^(RB)/2^(δ) in the formula(1-0) or (1-1).

Example Eight

In this example, the PTRS has an association with the SRS.

In one embodiment, when the time domain OCC of the SRS received by theterminal is enabled, or when the time domain OCC of the SRS belongs to apredetermined set, the terminal does not send the PTRS.

Alternatively, when the terminal is configured to send the PTRS under apredetermined condition (for example, a modulation order of a physicaluplink shared channel (PUSCH) is greater than a predetermined value),the time domain OCC of the SRS is disabled, or the time domain OCC ofthe SRS belongs to the predetermined set.

Through the solution in the above example, the uplink SRS adopts thetime domain OCC so that the coverage of the uplink measurement referencesignal is not affected while the capacity of the measurement referencesignal in a cell is increased. Moreover, the problem ofnon-orthogonality caused by two SRSs partially overlapping in frequencydomain when the SRSs are transmitted based on the ZC sequence can besolved. In addition, the time domain OCC is allowed to be associatedwith the relationship between the SRS and the time domain symbol in thepresent application.

Therefore, the time domain OCC, the cyclic shift parameter or the portindex of the measurement reference signal changes over time, whichreduces the signaling information, reduces the inter-cell interference,and increases the capacity of the measurement reference signal in thecell to a certain extent.

The frequency hopping bandwidth of the measurement reference signal mustsatisfy a certain constraint condition so that the terminal obtainsparameter information of the measurement reference signal according tothe restriction condition.

From the description of the embodiments described above, it will beapparent to those skilled in the art that the method of any embodimentdescribed above may be implemented by means of software plus ageneral-purpose hardware platform, or may of course be implemented byhardware. Based on this understanding, the technical solutions of thepresent disclosure substantially, or the part contributing to therelated art, may be embodied in the form of a software product. Thecomputer software product is stored in a storage medium (such as aread-only memory (ROM)/random access memory (RAM), a magnetic disk or anoptical disk) and includes several instructions for enabling a terminaldevice (which may be a mobile phone, a computer, a server, a networkdevice or the like) to execute the method according to one or moreembodiments of the present disclosure.

Example Nine

This example provides a channel quality acquisition method of ameasurement reference signal. The method includes the following steps.

A BWP is determined.

A hypothesis of a transmission parameter of a control channel isobtained according to a parameter of the BWP.

Channel quality information of the measurement reference signal isobtained according to the hypothesis of the transmission parameter ofthe control channel.

The parameter of the BWP or the transmission parameter includes at leastone of the following parameters: subcarrier spacing, a cyclic prefix(CP) length, or a frequency domain location in a carrier frequency.

In one embodiment, the BWP information is determined in one of thefollowing manners.

The BWP is determined according to a BWP in which frequency domainresources occupied by the measurement reference signal are located.

The BWP is determined according to BWP information in configurationinformation of the measurement reference signal.

The BWP is determined according to an agreed BWP, where the agreed BWPmay be, for example, a default downlink BWP or an initial active BWP.

The BWP is determined according to a BWP in which control channelresources corresponding to the measurement reference signal are located.

In one embodiment, the measurement reference signal includes at leastone of the following: a channel state information reference signal(CSI-RS), a demodulation reference signal (DMRS), a synchronizationsignals block (SSB), or a synchronization signal.

In one embodiment, for example, the terminal predicts and/or detectsperformance of beam transmission of a physical downlink control channel(PDCCH) using a CSI-RS resource by detecting the CSI-RS resource, andreports predetermined information to the base station when theperformance is lower than a predetermined threshold. For example, when ablock error ratio (BLER) of the PDCCH is predicted higher than 10%, theterminal reports beam recovery request information to the base station.

In order to obtain the predicted BLER of the PDCCH (also referred to ashypothetical PDCCH BLER), the transmission parameter of the PDCCH ishypothesized, where the transmission parameter includes at least one ofthe following parameters: subcarrier spacing, a CP length, or afrequency domain bandwidth in one carrier frequency. That is, thepredicted BLER is obtained based on the hypothesis that the PDCCH usesthe transmission parameter for transmission. In order to obtain thehypothesis of the transmission parameter of the PDCCH, a BWP may befirst determined, and a parameter of the determined BWP is then used asthe hypothesis of the transmission parameter of the PDCCH.

The BWP is acquired in one of the following manners.

The BWP is acquired according to a BWP in which frequency domainresources occupied by the CSI-RS are located.

The BWP is acquired according to BWP information in configurationinformation of the CSI-RS. For example, one piece of BWP information maybe configured in a CSI-RS resource setting in NR, which indicates a BWPin which all CSI-RS resources included in this CSI-RS resource settingare located, where one CSI-RS resource setting includes one or moreCSI-RS resource sets and one CSI-RS resource set includes one or moreCSI-RS resources.

The BWP is acquired according to an agreed BWP, where the agreed BWP maybe, for example, a default downlink BWP configured in NR or an initialactive BWP.

The BWP is acquired according to a BWP in which control channelresources corresponding to the measurement reference signal are located.For example, the CSI-RS has a qual-co-location (QCL) relationship with aDMRS of control resource set (CORESET) 1. The hypothesis of thetransmission parameter of the PDCCH is obtained by the parameter of BWPin which CORESET1 is located.

The CP length may also be referred to as CP type.
